Sadie Robertson shared her excitement about her upcoming prom dress line through Sherri Hill in a new photo on Instagram.

"So happy about my new prom dress line with @sherrihill coming out are y'all excited???" she asked her fans.

The teen debuted the "Sadie Robertson Live Original by Sherri Hill" line during New York Fashion Week 2013, and it appears more dresses may be available for purchase by the 2015 prom season.

The "Dancing with the Stars" runner-up has previously insisted that all of the dresses in the "Live Original" line will meet her father, Willie's, high standards.

"Me and my mother and my grandma went to Sherri Hill's place and we all picked out 'daddy-approved' length," Sadie told FOX & Friends last year. "She also added a couple inches to some that we loved but weren't modest."

In Robertson's new book, she discussed the joy of appearing in a NYFW fashion show, and also disappointment in how the models apparently treated her backstage.

The 17-year-old said she greeted the models with a "Hey, y'all," but "many of them did not say a single word back to me.

"They just looked at me like they had icicles in their eyes. Without using words, they sent me a strong message: 'What are you doing here?'"

The then 16-year-old said she took the cold reception in her stride, however.

"I could have totally lost it over the comments people made and the icy looks they gave me," she explained. "But I didn't. God had been training me all my life...to be strong and confident."
